Question

language c++

Hi i need help getting the out below i have include my code as well i have my main and then my functions but i dont know how to get the largest value of a vector i am stuck there. i need help making that and if you could please explain whats going on in that piece of code. also please correct any mistakes you see in my code. its a makefile .

Expected Output

My main

Functions

Calling function PopulateArray .. . Enter a unique integer value between 1 to 9 (q=quit) 2 Enter a unique integer value between 1 to 9 (q=quit) . 6 Enter a unique integer value between 1 to 9 (q=quit) . 7 Enter a unique integer value between 1 to 9 (q=quit) . 9 Enter a unique integer value between 1 to 9 (q=quit) 1 Enter a unique integer value between 1 to 9 (q-quit) 3 Enter a unique integer value between 1 to 9 (q-quit) Calling function GetLargest . .. The largest element value in the vector is 9

Explanation / Answer

To find largest value in the array/vector, first you need to declare a variable and assigne it with first value of vector

and then start traversing vector from index 1 or second element and compare it with alreadey existing value

in the varialble largest, if current vector value is larger than variable largest update it.

largest=vec.at(0);

if(vec.at(x)> largest)

{

largest=vec.at(x);

}

Sample Input/output:

Calling function populateArray...
Enter a unique integer value between 1 to 9 (q=quit).
2
Enter a unique integer value between 1 to 9 (q=quit).
6
Enter a unique integer value between 1 to 9 (q=quit).
7
Enter a unique integer value between 1 to 9 (q=quit).
9
Enter a unique integer value between 1 to 9 (q=quit).
1
Enter a unique integer value between 1 to 9 (q=quit).
3
Enter a unique integer value between 1 to 9 (q=quit).
q
Calling function Getlargest...
The largest element value in the vector is 9.
